SPECIFICATION forming part of Iletters Patent No. 317,717, dated May 12, 1885.

Application filed February 24, I885. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM BUNTING, J r., of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Water-Closets and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this application.

My invention relates to a new and useful improvement in that class or type of waterclosets in which is employed an earthenware bowl, the hollow open base of which is connected by some sort of couplingdevices with the upperend of aflexiblemetallic trap-leg and branch pipe leading off to the main soil-pipe.

Heretofore in this kind of water'closets' it has been customary to form the connection between the base of the earthenware part of the apparatus and the upper end of the metal pipe designed to conduct from the bowl its discharged contents) by means of an intermediately-arranged brass or other coupler, (of ferrule-like shape,) soldered at its lower end to the said metal conduit-pipe, and joined to the earthenware bowl-base by suitable clamping devices, an interposed rubber packing operating tomake the joint between the ferrule-like metal coupler and the porcelain bowl-base gas-tight. This method of and means for the connectingtogether of the bowl-base (or earthenware exit-pipe) and the metallic conduit-pipe has necessitated the making of two joints, of course-one by soldering together two metal parts, the other by packing together a metal and an earthenware surface.

I purpose by my invention to very much simplify the construction of this kind of watercloset apparatus by making only one connection or joint directly between the open base of the earthenware portion of the closet and the upper end of the metallic pipe which communicates with said base portion and to this main end and object my invention may be said to consistin the combination, with the earthenware base of the bowl and the upper end of the metal conduit-pipe, of suitable means making a gas-tight joint between these parts, all as will be hereinafter more fully explained, and as will be more particularly pointed out and defined in the claim of this specification.

To enable those skilled in the art to which my invention relates to make and use watercloscts containing my said improvement, I will now proceed to more fully describe the latter, referring by letters to the accompanying drawings, which form part of this specification, and in which I have illustrated my invention carried out in that form which is the best now known to me, and in which I have so far successfully practiced it. I In the drawings, Figure 1 is a vertical sectional view of a closet-bowl and its lower metallic connections embracing my invention. Fig. 2 is a partial similar section, but on an enlarged scale, to better show the shapes and arrangement together of the parts. Fig. 3 is a detail bottom view of the earthenware base or bottom portion only ofthe bowl. Fig. 4 is a detail plan or top view of the flanged clamping-plate, and Fig. 5 is a perspective View of the rubber packing-rim employed.

In the several figures the same part will be 'found designated by the same letter of reference.

E is the open base of the earthenware bowl A, made in one of the usual forms, and e is the upper portion of the metal pipe that contains the trap 0 and extends, by a bran-ch portion, 8, to the ordinary soil-pipe.

K (See Fig. 2) is a metal face-plate, which is about equal in extreme diameter to the diameter of the base E, and which is formed with an upwardly-projecting flange, f, at the edge of its central circular opening, which latter is a little larger than the exit-opening in the base E of the bowl, and large enough to easily permit the passage through it of the cylindrical part of the upper portion, 6, of the metal conduit-pipe. This pipe (which is usually composed of lead) has its upper edge turned over the flange f of the plate K, as seen at b, and the baseE of the earthenware bowl has formed in it, at 0 an annular groove or recess of somewhat the same shape (in cross-section) as that of the flange f of plate K.

Between the upper portion or apex of the annular flange f and the surface of the circular groove or recess 0 of the base E is placed a rubber gasket or packing-ring, 0, all as clearly seen at Fig. 2.

Through suitable holes in both the metal IOO plate Kand the earthen ware baseE are passed screw-bolts N, by means of which and their nuts n the circular plate K and the circular base E are forcibly drawn or clamped together, as shown. WVhen thus secured together, the turned over upper end, I), of the lead pipe 6 and the rubber ring 0 are forcibly clamped or compressed betweenthe upper edge of the metal flange f of plate K and the hollowed-out seat or recess 0 of the earthenware base E, thus making a perfectly-tight joint between the upper end, I), of the metal pipe and the base E of the earthenware portion of the water-closet.

All soldering or othernon-detachable means of jointure between the metal pipe e and the porcelain base E is avoided, and a single clamp-like, joint accomplishes all that is required in the type of closet shown.

Of course, the precise shapes and propori tions of the packingrin g, the grooves in which its is seated, the flange f, and the turned-over upper end, b, may be more or less varied without changing the principle of construction or the mode of operation of the oontrivance shown, and hence without departing from the spirit of my invention.

.The turned-over upper end, b, and the upper part, c, of the metallic pipe shown, being made,

asusual, of lead, are sufficiently pliable or flexible to permit any reasonable amount of change in relative position therewith. of the plate K and base E (in consequence of the usual settling of the house, &e.) without any liability of loosening the joint formed where the rubber ring 0 is clamped between the top of flange f and the root of the groove 0 and by simply taking out and replacing the bolts N and nuts a the parts can always be easily disconnected and again put together in a perfectly gas-tight condition.

Having now so fully explained my invention that any one skilled in the art can make and use water-closet apparatus containing my improvement, what I claim as new, and desire to secure by Letters Patent, is-

' In combination with the lowermost part or open base of an earthenware closet-bowl and the upper end of a flexible metallic exit-pipe, (communicating with the exit-orifice of said open base,) a metallic plate adapted to be secured to said base and press upwardly on the turned-over upper end of said exit-pipe, and apacking-ring interposed between said turnedover portion of the exit-pipe and the lower surface of the earthenware base, substantially as set forth. t

In witness whereof I have hereunto set my hand this 26th day of December, 1884.
